GRAlN-SHOCKER.

SPEGIFIQATION forming part of Letters Patent No. 747,195, dated December15, 1903.

Application filed August 11, 1902. Serial No. 119.321. (No model.)

To all whom it'mcty concern:

Be it known that I, CHARLESE. LOVER- CHECK, a citizen of the UnitedStates,"residing at Hebron, in the county of Thayer and State ofNebraska, have invented a new and useful Grain-Shocker, of which thefollowing is a specification.

The object of my invention is to provide an improved mechanism forreceiving bundles or sheaves of grainsuch as wheat, rye, or thelike-from a binding-machine and assembling the same to form a shock,such shocks being deposited on the ground at intervals and each shockcontaining precisely the same number of sheaves.

A further object of the invention is to insure the deposit'of theassembled shocks in proper position on the ground without stopping thetravel of the binder or the shocker.

A still further object of the invention is to so construct the mechanismthat all of its connected parts may be operated automatically from thegrain-binder and without the necessity of employing any manual laborwhatever.

With these and other objects in View the invention consists in the novelconstruction and arrangement of parts hereinafter described,illustratedin the accompanyingdrawings, and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 is a side elevation of agrain-shocker constructed in accordance with my invention, the partsbeing shown in the position assumed during the assembling of the sheavesto form a shock. Fig. 2 is a longitudinal sectional elevation of thesame, illustrating the position of the parts after a shock has beendeposited on the ground and the shock-engaging devices have beenelevated preparatory to the return movement to initial position. planview of the device on the line 3 3 of Fig. 2. Fig. 4 is an elevation,partly in section, looking from the front end of the machine.

Fig. 18 is adetail perspective View of aformer to be placed at the center of theplatform at the beginning of the shock-forming operation. Fig. 19 is adetail sectional view of the head of the former. Fig. 20 is a sectionalelevation of a portion of the operating mechanism shown inFigs. 8

and 10, the parts being illustratedin differbars 11, connected at theirupper ends by a series of timbers or metal bars to form asupporting-frame for that portion of the mechanism employed fordepositing the shock of grain on the ground. The'shock-assemblingmechanism is disposed on the horizontal portion of the frame at a pointclose to the grou nd,

so that the shock may be more readily and safely discharged. Thehorizontal side sills 14 of the frame form guideways for the receptionof antifriction-rollers 15, mounted on studs or spindles projecting froma rectangular frame 16, the latter serving. as a support for a revolubleshock-assembling platform 17. The transverse bars 18 of the frame 16 areconnected to each other and provided with pivotal bearings for thereception of a pair of vertically-disposed shafts 19 and 20, the latterbeing located at the center of the platform 17 and forming a pivot onwhich said platform revolves. The two shafts are pro vided withsprocket-wheels 21, connected by a link belt 22, and an intermittentrotative movement is imparted to the shaft 19 through the medium of apawl 23, adapted to engage with a ratchet-wheel 24, secured to theshaft. The teeth of the ratchet-wheel are of a nu mber equal to thenumber of sheaves to be assembled in each shock, and after saidratchetwheel has received one complete rotation the platform is providedwith a sufficient number of sheaves to form a shock, which is thenautomatically deposited on the ground. The

ratchet-wheel is rotated to the extent of a single tooth by eachoperation of the mechanism, which receives the successive sheaves fromthe binder and deposits the same on the platform. At one side of thehorizontal portion of the frame is a lateral-projecting bracket 26, anda short distance in front of the bracket 26 is a second bracket 27,these two brackets being provided with bearings for the reception of ashaft 28, extending longitudinally of the machine and provided with asprocket-wheel 29, which is loosely mounted on the shaft and receivesconstant motion from the grain-binding machine through the medium of alink belt 30. To the hub of the sprocket-wheel is rigidly secured amiter-gear 31, intermeshing with a similar gear 32, carried by a stud33, projecting from the upper surface of a bracket 26. The head of thestud projects beyond and above the miter-gear 32 and is provided with arecessed lug 34, to which is pivoted an arm 35, the latter beingoperated in such manner as to receive both a vertical and an oscillatorymovement in the manner hereinafter described.

At the outer end of the arm 35 is pivoted a block 36, which may be movedto either a horizontal or vertical position, and on said block arearranged two upwardly-extending lugs 37, to which is pivoted a bracket38, having at its opposite ends a pair of transverselydisposed bars 39.The bars 39 form bearings for two parallel shafts 40 and 41, to each ofwhich are secured a number of curved tines or prongs 42, saidtines orprongs being so arranged that when in receiving position below thedischarge-throat 0c of the binder they will form a substantiallysemicircular trough or basket for the reception of a sheaf of grain. Theshafts are provided with intermeshing pinions 43, with one ofwhichengages a pawl 44, adapted to hold the two'shafts in any position towhich they may be adjusted. The pawl is of the gravity type, beingprovided with a counterweight 45, which projects for some distance belowthe transverse bars 39, and at the delivery-point, where the sheaf isdeposited on the platform, this pawl is automatically tripped to permitthe return of the tines to sheaf-receiving position.

Depending from the shaft 40 is a pin 44, Fig. 5, which when the arm 35is moved from the position shown in full lines to that indicated indotted lines in Fig. 3 will at the beginning of the movement engage ablock or stud 45, projecting from the side of the frame, and cause aslight rotative movement of both shafts, the tines being thus forcedinwardly and closing around the sheaf of grain, holding the same firmlyduring the movement toward the assembling-platform. When the tines areclosed together, they are held by the pawl 44, and when the latter isreleased the tines are opened out by means of a helical torsion-spring46, coiled around a portion of the shaft 40 and having one end securedto said shaft and its opposite end to one of the transverse bars 39.

To the inner end of one of the bars 39 is swiveled one end of a rod 47,the opposite end of which is connected to an eye 48 on the upper surfaceof the arm 35, and to the lower portion of the block 36, at a pointbeyond the pivot-pin of the latter, is connected one end of a rod 49,having its opposite end pivotally connected to an eye 50, pivoted on thebracket 26. When the arm 35 is turned, with the stud 33 as a center, thetines are closed together on the sheaf of grain, as previouslydescribed, and as the movementof the arm continues the connecting-rod 49between the block 36 and the bracket serves to gradually turn said blockto a vertical position, the two shafts 40 and 41 being similarly movedand the sheaf of grain raised to a vertical position, so that its lowerend or the bottom of the sheaf may come into contact with thereceiving-platform. On the movement of the arm the connecting-rod 47between the crossbar 39 and the arm 35 serves to swing the upper bar 38on the pivot-pin which connects it to the lug 37, the plane in which thetwo axes of the shafts 40 and 41 are situated being then substantiallyvertical or at a right angle to the longitudinal axis of the machine.The tines thus present the sheaves properly to the platform, and thedischarging movement is effected by the contact of the counterweightedportion 45 of the pawl 44 with one of the pivotal lugs 37, the shaftsbeing then partly rotated by means of the torsionspring 46 and the tinesopened to release the sheaf. As the horizontal plane of the arm 35 isbut a trifle above the plane of the'platform when in receiving position,it becomes ICC necessary to slightly elevate the outer end of framesvertical position, and this is accomplished by means of a curved bar 51,carried by the bracket 26 and arranged to form an ascending plane, onwhich the arm 35 rests during its oscillatory movement.

The rocking movement of the arm 35 takes place through an angle of aboutninety degrees, and in order to gain this intermittent oscillatorymovement from the continuouslyrevolving miter-gear 32 said arm isprovided with a rearwardly-extending lug 52, carrying avertically-adjustable pin 53, adapted to engage in any one of a seriesof openings 54:, formed in the upper surface of the mitergear 32. At apoint on the bracket adjacent to the position assumed by the lug 52 whenthe arm 35 has completed its inward movement is an arm 55, having itsupper surface inclined and adapted to engage a projecting tongue at thetop of the pin and raise the same from engagement with the opening inthe miter-gear, thus releasing the arm and permitting the latter toassume an initial position through the medium of a tensionspring 56.When the pin 53 is raised from engagement with one of the openings inthe miter-gear, a recess 55' in said pin is brought into alinement witha locking-dog 56, movable in a radial slot or opening in the end of thearm 35 and normally held in position to engage the slot of the pin by asmall compression-spring. The dog is provided with an upwardly-extendinglug, with which may engage an arm 57, operated by a rod or cord 57 fromamovable member of the binder-throat or at any other convenient pointfrom Which movement may be transmitted to effect the release of the dogfrom the pin as soon as a sheaf is dropped into the tines carried by thearm 35. When the arm is revolved to sheaf-delivery position, the pin 53is raised from the miter-gear and is held locked in elevated position bythe locking-dog 56 during all the time the tenison-spring 56 is actingto return the arm to initial position and is held elevated until suchtime as the prongs receive a sheaf from the binder, the arm 57 beingthen automatically operated to release the dog and permit the pin todrop in readiness to enter the first of the openings 54 which may passbelow the pin. When the arm has been moved to a position to deliver asheaf of grain to the platform, said sheaf is in a position immediatelybetween a pair of curved arms or bars 58, carried by vertical standards59, projecting upwardly from the platform carrying frame 16, the guardsbeing held stationary and serving to properly support the sheaves as thelatter are successively delivered to the platform. Each timeasheaf ofgrain is delivered to the platform the ratchet-Wheel 24: is revolved tothe extent of a single tooth, and to accomplish this result theactuating-pawl 23 is pivotally connected to a pivoted bar 60, the outerend of which projects through an opening in one of the sills 14 and isengaged by a reciprocating block 61.

The block 61 is connected by the link. 62 to the arm 35, and as thelatter is on its delivery movement said block receives a movementsufficient to move the pawl 23 in the direction of the rear of themachine to engage a fresh tooth. This movement takes place against thestress of a compression-spring 63, which during the return movement ofthe arm returns the lever to its initial position, the pawl moving theratchet-Wheel to the extent of a single tooth and a similar movementbeing imparted to the connecting sprocket-wheels and link belt to thereceivingplatform, so that a fresh space is left for the reception ofthe next sheaf of grain. When the last sheaf of grain necessary to formashock has been placed on the revoluble platform, it becomes necessary tooperate the shock-delivery mechanism and to reciprocate the platform.This is accomplished by the following mechanism: On the normallystationary shaft 28 is keyed a collar 70, having a projecting lug towhich is pivoted an arm 71, having one end slightly recessed or rounded,as indicated at 72, for the reception of one or other of a pair ofprojecting pins-73, extending fromthe sprocket-wheel 29. This end of theclutch-arm 71 is normally held out of the path of movement of the pinsby means of a rocking arm 74, carried on a rock-shaft 75, the end of thearm 71 being inclined, as illustrated more clearlyin Fig.9,at that pointwhere it comes into contact with the rocker-arm. At a convenient pointon one of the side sills of the framework is a spindle 76, carrying aratchet-wheel 77, having one tooth in excess of the number of teeth ofthe platform ratchet- Wheel 24, the latter being provided in the presentinstance with eight teeth and the platform being adapted to receiveeight sheaves of grain to form each shock, while the ratchet-wheel 77 isprovided with nine teeth for a purpose presently to be described. Fulcrumed to the ratchet-wheel spindle is an arm 78', carrying a pivoted pawl79, adapted to engage the teeth of the ratchet-Wheel. This arm isdisposed in the path of movement of a tongue 80, arranged below the arm35 and movable with the miter-gear 32 as each sheaf is delivered. Whenthe arm is moved to delivery position, the tongue 80 comes into contactwith the arm 78 and moves the latter toward the rear of the machineagainst the stress of a tension-spring'81, the movement being to theextent of a single tooth, and when the arm is released by the returningmovement of the sheaf-delivery arm the spring 81 returns thepawl-carrying arm to its initial position and revolves the ratchet-Wheelto the extent of a single tooth, this movement occurring eight timesduring the formation of each shock and the ratchet-wheel receivingeight-ninths of a revolution. To the spindle 76 is secured a notcheddisk 82, the notch being arranged in alinement with theeighth tooth ofthe ratchet Wheel, and after the latter has been moved a sufficientnumber of times to form a shock the notch is moved opposite to an arm 83on the rock-shaft 75, said arm entering the notch and serving to raisethe arm 74 from engagement with the clutching-arm 71 and permit thelatter to assume the dotted-line position shown in Fig.

1 9, with the recessed end 72 in the path of movement of one or other ofthe clutchingpins carried by the sprocket-wheel 29. In this position theconstantly-rotatin g sprocketwheel 29 will engage the arm 71 through themedium of the pin 73 and will transmit power to the normally stationaryshaft 28, this latter shaft being provided with connections fortransmitting movement to the remaining portions of the mechanism. Thearm 83 remains in the recess of the disk during all the time theplatform is moving to the full forward position shown by dotted lines inFig. 3 and then back again to the rear or sheaf-receiving position shownin full lines. When the platform is about stopping on its rearwardmovement, a pawl 85 on the platform engages the ratchetwheel 77, movingthe same to the extent of asingle tooth, and thus forcing the recessedportion of the disk out of alinement with the arm 83 and returning thearm 74 to the position shown in full lines in Fig. 9, the ratchet-wheelbeing adjusted to such position as on the next eight movements necessaryto the completion of a fresh shock the recess will again be moved to aposition in alinement with the arm 83. When the arm 74 assumes thefull-line position, the continued transmitting pin 73.

movement of arm 71 will bring the inclined end of the latter intocontact with the end of arm 74, resulting in a camming action, whichrestores the arm 71 to the position indicated in full lines in Fig. 9and removing its recessed end from engagement with the power- The shaft28 is then stopped and remains stationary until the next engagement ofthe clutch.

At'one side of the main frame is the open bracket or frame 27, having abearing for the reception of one end of the shaft 28, said shaftcarrying a bevel-gear 91 at a point within the frame. The frame hasbearings for the reception of a transversely-disposed shaft 92, on whichslides asleeve 93, the latter being feathered to the shaft, but free forlongitudinal movement thereon. On the sleeve is a loose bevel-gear 94,and on the shaft is a similar bevel-gear 95, both of which intermeshwith the gear 91, fixed to the shaft-28, and are rotated by said gear inopposite directions. These loose gears 94 and 95 may be held fromlongitudinal movement in any suitable manner, as by clips 96, carried bythe frame and extending into annular grooves formed in the hubs of therespective gears. The hub of the gear 94 is provided with one or morerecesses 97, and similar recesses 98 are formed in the adjacent face ofthe hub of the gear-wheel 95. These recesses serve to receive a pin 99,carried by a sleeve 93, the latter being longitudinally adjustable toengage said pin with the recesses of either'wheel, and thus effect therevoluble movement of the shaft 92 in either direction.

On the shaft 92 is secured a pinion 100, which intermeshes with a rack101, carried by the platform-frame, the platform by this means beingmoved to either of the two positions indicated in Fig. 3. The shiftingmovements are automatic and are accomplished by the movement of theplatform, the latter being provided with suitable tripping devices andother actuating mechanism for automatically shifting the positions ofthe clutching mechanism and various other parts of the apparatus, themovement of which must be timed to correspond with the movement of theplatform.

The construction of the automatic clutchshifting mechanism is best shownin Figs-12 and 13. The slidable sleeve 93 is provided with a groovedcollar 102 for the reception of the bifurcated end of a clutch-lever103, pivoted to a stud 104, projecting from the frame of the machine.The clutch-lever has three positions in which it may be locked by apivoted latch 105, having three lever-receiver openings 106, 107, and108, there being suitable mechanism for automatically raising the latchwhen the movement of the platform is to be started in either directionand, further, to provide for the shifting of the clutch-lever as theplatform nears the limit of its travel in both directions. Theclutch-lever 103 is provided with a suitable opening for the passage ofthe lower arm of a U-shaped sliding bar 109, adapted to suitableguiding-openings in the fixed frame, compression-springs and 111 beingplaced on the said lower arm on opposite sides, respectively, of theclutchlever, the movement of the latter in one direction compressing oneof the springs and relaxing the other, and vice versa. Projecting fromthe inner faceof one of the sills are two guides 112 for the passage ofa longitudinally-movable shifting bar 113, which extends parallel withthe sill for the greater This bar passes between a pair of antifric-.

tion-rollers 115 on the upper arm of the U- IIO shaped bar 109, and asthe bar 113 is moved longitudinally these rollers may be made to ascendand descend the inclined plane in order to compress one or other of thesprings 110 111. The bar is further provided at opposite ends withfingers 116 and 117, arranged in difierent planes and adapted to beoperated upon by projections on the carryingframe of the platform. Theinitial position of the platform or that in which the sheaves areassembled to form a shock is that shown in full lines in Fig. 3, and inthis position the clutch-lever 103 is in the central notch 107 of thelatch-bar,the spring 110 being compressed and the clutching-sleeve 93being in mid-position and disengaged from both of the bevel gears. Whena sufficient number of sheaves have been assembled to form a shock, thelatch-bar 105 is released by means of a bellcrank lever 118, pivoted tothe sill and having one arm connected by a cord or chain 119 to anoperating mechanism, hereinafter described. This mechanism isautomatically set into operation at the proper moment, and the latch-baris raised from the clutch-lever 103, the latter being then thrown in thedirection of the notch 108 by means of the compression-spring 110. Thelatch-lever is re leased immediately, being only momentarily raised topermit the disengagement'of the clutch-lever from the central notch, andsaid clutch-lever is then caught and retained by the notch 108. Themovement of the clutch- .lever in this direction causes a correspondingmovement of the sleeve 93, the pin 99 being moved into engagement withthe recessed face of the bevel-gear and clutching the same to the shaft.This movement operates the shaft 92 and pinion and results in themovement of the platform toward the dottedline position of Fig. 3.Immediately before the platform reaches the dotted-line position adependinglug 120 on the platform-frame engages the finger 117 of bar 113and draws the bar forward, causing the rollers 115 to ascend theinclined plane 114 and resulting in'an outward movement of the U-shapedbar 109. This movement causes the spring 111 to be compressed, while thespring 110 is now wholly relaxed. When the rollers have reached the topof the inclined plane of bar 113, the finger 117 is disengaged from thelug 120 by contact with a projecting cam-block 121 on theinner face ofthe frame-sill,the finger being turned and slightly depressed to a pointbelow the lug 120. The platform continues on its rearward movement solong as the clutchlever 103 remains in the notch 108; but as the limitof movement is reached a pivoted cam 122,carriedby the frame of theplatform,comes into contact with a projecting lug 123 at the end of thelatchbar, raising said latch-bar from engagement with the clutch-leverand permitting the movement of the clutch-lever to mid-position underthe action of the spring 111. This moves the clutching-sleeve 93 to midposition and the parts remain stationary until it becomes time to startthe rearward movement. During the movement of. the platform to the frontthe shock has been deposited on the ground by mechanism hereinafterdescribed, and as this mechanism completes its operation the bell-cranklever 118 is again automatically tripped and raised into contact withthe latch-lever 105. The spring 111 at this time is still compressed toan extent sufficient to cause a movement of the clutching lever in thedirection of the notch 106, and when this occurs the clutching-sleevehas been moved until the pin 99 engages with the recessed face of thebevelgear 94, and the shaft 92 and pinion 100 are rotated in a directionopposite to the previousdescribed movement, the platform being 1 movedto the rear and returned to initial position. As the platform approachesthe limit of its rearward movement a lug 120 on the under side of theplatform-supporting frame comes into contact with the finger 116, movingthe bar 113 to the rear and causing the rollers 115 to descend'theinclined plane 114, and thus compress the spring 110, the spring 11being at this time wholly relaxed. As the platform nears the limit ofits rearward movement a pivoted pawl 122 on the platform-frame comesinto contact with the lug 123 on the latch-bar and raises the same momentarily, permitting the clutch-lever to pass from the notch-106 to thenotch 107 under the influence of the spring 110. This again moves theclutching-sleeve to mid-position and stops the platform at the propermoment, the clutch-lever being in mid -position and the spring 110 stillcompressed to an extent sufficient to throw the clutch-lever from thelocking-notch 107 to the notch 108 on the next cycle of operation.

At the upper end of the frame 11 are suitable bearings for the supportof the two-part shaft 130, having at one end a sprocketwheel 131, whichis connected by a link belt 132 to a sprocket-wheel 133, the latterbeing secured on the elongated hub of the bevelgear 95, Fig. 11, thesprocket-wheel receiving continuous motion in the same direction duringall the time the shaft 28 is clutched to the sprocket wheel 29. On theshaft is a gear-wheel 134, intermeshing with a gear 135 onacounter-shaft 136. The counter-shaft 136 carries a fixed gear 137 and aloose windingdrum 138, which may be clutched to the shaft by aclutching-sleeve 139 under the control ofa bell-crank lever 140, and themovement of the bell-crank lever is controlled by the winding andunwinding of a cord or chain 141 on the drum 138. The cord or chain 141passes up over a sheave 142 at the upper end of a standard 143, forminga part of the frame. The opposite end of the cord or chain is connectedto a shock support or former 145,which is placed at the center of theplatform prior to the delivery of the first sheaf of grain and assistsin properly holding the sheaves together during the formation of theshock. When the shock is assembled and prior to its delivery, thisformer is removed from its position, so that the shock engaging anddelivering tines or forks may properly operate. The former comprises avertical spindle 146, arranged over the center of the platform andhaving at its lower end a swiveled head 147, provided with a lowerrecess 148 for the reception of a vertically-movable bar 149, which atall times maintains a position in axial alinement with the head andspindle. Pivoted to the lower portion of the head are a number of legs150, which when the spindle is lowered are engaged by inclined shoulders151, formed at the upper portion of the vertically-movable bar 149,- thelegs being thus spread in the form of a tripod and forminga IIO of thespindle 146.

support for the center of the shock. When in operative position,with allof the legs and the central bar resting on the center of the platform,the legs and bar rotate freely with the platform, owing to the swiveledconnection between the head 147 and the lower end When the spindle iselevated, at the completion of a shock, the inclined shoulders 151remain in lowered position, and on the further upward movement of thespindle the arms are closed together by gravity, so as not to disturbthe sheaves of grain during the removal of the former. The normalposition of the former is that illustrated in Fig. 1, the legs beingspread and resting on the central portion of the platform. At this timethe clutch 139 is held in clutching engagement with the winding-drum 138by means of a projecting collar or block 154, arranged on the cord orchain 141 and in position to operate the winding-drum as soon as theshaft 28 is clutched to the sprocket-wheel 29. When this clutchingoperation occurs,motion is transmitted through the gearing connectionsto the counter-shaft 136, and the cord or chain is wound on the drum,the shock-former 145 being elevated until the upper end of the spindleassumes the position shown in Fig. 15. The spindle 146 is provided witha projecting pin 155, adapted to be engaged and held by one arm of aT-shaped lever 157, pivoted on the standard 143, the lever beingnormally held in looking position by the tension of the cord or chain141 against the outer end of one of the lever-arms 158. On the upwardmovement of the spindle the stud or pin 155 passes the inclined face ofthe lever, and the latter .is forced by the tension of the winding-cordto a position under the roller or pin and serves to hold the sameelevated. At the completion of the winding movement a block or similarprojection 160 on the cord or chain comes into contact with a bell-cranklever 140 and moves the clutching -sleeve away from the drum, the drumremaining stationary on the counter-shaft 136.

The removal of the shock-former 145 is the first operation subsequent tothe application of power to the shaft 28, and said former is maintainedin its elevated position during the removal of the shock from theplatform and during the traveling of the platform to the full forwardposition and back again to the initial position to receive sheaves forthe formation of another shock. As the platform nears the limit of itsrearward movement to normal position a projecting pin 165 on saidplatform comes into contact with one arm of a bell-crank lever 166,mounted on the fixed frame, the opposite arm of said bell-crank leverbeing connected by a flexible cable or chain 168 to the T-shaped lever157, said cable or chain being guided over a sheave 170, mounted on asuitable standard 171 at the upper portion of the framework. When thele- Ver is tripped by this movement of the platform, the shock-formerdescends by gravity to its normal position, the winding-drum beingdisconnected from the shaft and offering no resistance to the downwardmovement of said former. At the conclusion of the downward movement ofthe former the projection or block 154 on the chain or cord 141 is movedinto engagement with the under side of the horizontal arm of thebell-crank lever 140 and results in the clutching of the sleeve 139 tothe winding-drum. When this occurs, the clutch connecting the shaft 28to the sprocket-wheel 29 has been disengaged by the mechanismhereinbefore described, the counter-shaft 136 being stationary at thistime, so that the winding-drum, while clutched to the shaft, will not beactuated until on the completion of a shock the shaft 28 is again setinto operation.

The upper framework may be considered as divided into inner and outermembers, between which are formed two longitudinallydisposed slots 174for the passage of a rectangular frame 175, the opposite sides of theframe being provided with suitable antifriction-rollers 176, adapted totravel on guideways 177, there being one of such guideways at each sideof the frame. In the inner frame members are journals for the support oftwo sets of shafts 178, there being four of such shafts in each set andeach shaft carrying a sprocket-wheel179, over which extends a link belt180, arranged in substantially rectangular form and following thecontour of the guideway 177. From the inner face of each side of theframe projects a small bracket 181, which is connected to one of thechain-links, the connection insuring a movement of the frame 175, withthe belts, through a cycle of operations including, first, a downwardmovement; second, a rearward movement; third, an upward movement;fourth, a forward movement to the initial position, being the positionindicated in Fig. 15. To impart the necessary movement to the two linkbelts, two of the shafts 178 are extended through the supporting-frameand at their inner ends are provided with sprocket-wheels 183, connectedby link belts 184through sprocketwheels 185 on the shaft 130, and whenthis section of the shaft is clutched to the section IIO carrying thesprocket-wheel 131 the necessary movement is imparted to the two sets oflink belts carrying the frame 175, and the latter begins its movement toeffect the removal of the shock from the platform and the delivery ofthe same to the ground.

To one of the shaft-sections 130 is secured a clutching-sleeve 186, andto the opposite vided with two arms 191, to which are'pivoted slidablebars 192, adapted to guides at the top of the frame and having theirrear ends in the path of movement of lugs 193, carried by the frame 175,said lugs engaging with the bars each time the frame 175 reaches thelimit of its forward movement in assuming the normal positionillustrated in Fig. 15. When the lugs engage the bars 192, the latterare forced forward, and on depressing the arm of the bell-crank lever188 the clutching-sleeve 187 is disengaged from the clutching-sleeve 186and one section of the shaft 130 becomes stationary and stops themovement of the link belts 180. The clutch is held disengaged until suchtime as it becomes necessary for the frame 175 to start into operation,and at this time one of the bars 192 is engaged by one arm by thebell-crank lever 195, pivoted to the frame, the opposite arm of saidlever being connected by a cable 196 with a bell-crank lever 197,fulcrumed on the main frame. The platform'frameis provided with a lug198, which just before the platform reaches the full forward position(indicated by dotted lines in Fig. 3) engages the lever 197, which isconnected to the bellcrank lever 197 by acord 196, and raises thebell-crank lever 195, the latter elevating the bars 192 above the lugs193 of the frame and permitting a clutching movement of the sleeve 187under the influence of a spring 198, the shaft-sections being thusconnected together and motion imparted to the link belts and the frame175, carried thereby.

To the lower portion of the frame 175 are secured two bars or plates198, carrying pivot-pins 199, on which are hung fork-arms 200 201, saidfork-arms being each provided with elongated tines 202, arranged oncurved bars 203 in order to conform to some extent to the contour of theapproximately circular shock carried by the platform. At the upper endof each fork-arm is a gear-segment 204, and between these two segmentsis mounted a double rack-bar 205, adapted to engage with and operateboth segments at the same time, a down ward movement of the rack-barcausing the opening of the forks and a movement in the oppositedirection causing the forks to close upon the shock. To the fork-arm 200is pivoted a shock-clamp in the form of a bar 206 having at its lowerend a pair of approximately semicircular bars 207,which engage the shockin advance of the forks and during the disengagement of the forks fromthe shock serve as strippers to prevent the overturning of the shock.The rear clamp-bar 206 when in normal position, or in that positionwhere the platform is receiving the sheaves to form a shock, is loweredto the position indicated in Fig. 15 and acts, in connection with thepreviously-described guard 58, as a support for the sheaves during theshock-forming operation. When the fork-arms descend from the positionshown in Fig. 15 to engage the shock, a pin 209 on the clamp-bar isautomatically engaged by a catch 210, pivoted on the forkarm 200, andwhen said fork-arm is disengaged from the shock said catch serves toelevate the clamping-arm with the fork-arm and raise the same clear ofthe shock. To the front fork-arm 201 is connected a clampingbar 210,carrying curved clamps similar to those on the bar 206 and bearingcorresponding reference-numerals. The bar210' is connected to thefork-arm 201 in such manner that it normally maintains a position inadvance of or below the fork-arm, the bar being formed of a piece ofspring metal which when the fork-arm is forced into engagement with theshock will yield until the clamping-bars are pressed against the bar201. The clamping-bar 210 acts as a stripper for the forks carried bythe arm 201 in that on the disengaging movement of the fork-arm 201 thespring-bar 210 will retain its position against the shock until thetines are fully withdrawn, after which the continued upward movement ofthe fork-arm will also elevate the clamping-bar.

The rack-bar 205 is provided on each side with an antifriction-roller211,adapted during its reciprocating movement to travel in contact withupper guides 212, disposed parallel with the upper run of the link belts180 and lower guides 213, arranged at an angle to the lower run of saidlink belts. When in the position shown in Fig. 15, the weight of thefork-arms would naturally-tend to elevate the rack-bar 205 by gravity;but this is prevented by the latch 214 forming a continuation of theupper guide 212 for the rack-bar antifriction-rollers, said rollers atthe completion of the forward movement of the rack-bar passing beyondthe end of the guideways 212 and coming into contact with the latch 214.The latch 214is guided in the frame and main tainedin locking positionby a tension-spring 215. To the outer end of the latch is connected onearm of a bell-crank lever 216, hung on a bracket on the frame, theopposite arm of said bell-crank lever being bifurcated for the passageof the cable or chain 141, and said cable or chain is provided with anenlarged block 217 or similar device which at the proper moment isbrought into operative engagement with the bell-crank lever to removethe latch 214 from contact with the antifrictionroller 211 of therack-bar. This movement occurs when on the winding movement of the cable141 the spindle of the shock-former 145 has reached its highestposition, and as soon as the latch is withdrawn the weight of thefork-arms causes the rack-bar to ascend, the forks dropping into contactwith the shockand the tines being partly entered in the sheaves. Whenthe rack-bar reaches its limit of upward movement, a pivoted dog 220,carried by said bar, engages a pivoted arm 201, carried by a standard171, and said pivoted bar is connected to the cable 119, which, aspreviously described, extends to the bell-crank lever 118 under thelatch bar 105. This movement releases the. latch and permits theclutch-lever 103 to move into engagement with the inner notch 108 of thelatchbar, the platform-actuating shaft 92 being clutched to thebevel-gear 95 and the platform started on its movement toward the frontof the machine. Before the front is reached, however, the bell-cranklever 192 is elevated to release the clutch-sleeve 187 and permit thelatter to engage the clutchsleeve 186 on the shaft 130 and start themovement of the link belts 180 and the frame 175. Previous to this,however, the dropping of the fork-arms to engagement with the shock hasresulted in the bringing of a segment222 on the pivot or stud of therear fork-arm into engagement with the revolving gear-wheel 137 and thelatter has positively forced the forks into engagement with the shock,the movement of the gear-wheel being transmitted, through the segment222 and the front fork-segment, to the rack-bar and the rearfork-segment, and at the end of the movement the releasing movement ofthe bar 221 occurs to start the platform toward the front. At this timethe clutching mechanism connects the bevel-gear 95 to the shaft 92 andthe pinion 100 is engaging the rack 101 and moving the platform towardthe front from underthe shock, the latter being firmly held andsupported by the forks.

As the platform nears the limit of its forward movement the link belts180 are set into operation in the manner previously described and theframe 175 moves down until the shock is in contact with the ground, andthence, the machine continuing its forward movement, the frame isstarted on a rearward movement with the lower run of the link belts,thespeed being approximately the same as the forward speed of travel of themachine, so that the shock will practically remain in a stationaryposition. As soon as the shock touches the ground the rollers 211 of therack-bar are engaged with the inclined lower guides 213, and as therearvward movement of the forks and rack-bars continue the rack-bar isgradually depressed and through the segments gradually ele vates the twofork-arms, the stripper-bars 206 and 210 remaining in engagement withthe sides of the shock until the tines of the forks are fully removed,after which the strippers or clamps are also elevated, the full openmovement being reached at the time the rollers 211 arrive at the rearend of the guides 213. At the upward run of the belt, or the verticallift, which occurs after the antifriction-rollers leave the inclinedplane 213, the fork-arms are maintained in open position by friction,there being insufficient time to permit the falling of the fork-armsbetween the time the rollers leave the inclined plane 213 and engagewith the upper guides 212. The shock is thus left carefully on, theground and the forks removed and elevated in such manner as to preventthe ing the normal position.

accidental toppling of r the shock. As the movement of the frame 175continues the rollers.211 travel along the guideways 212 and thenceunder the latch-bar 214,'assum- Immediately before the partsreach theposition shown in Fig. 15 the catch 210, which supports the rear clampbar 206 in position, is engaged bya stud 224,

extending from the fixed frame, the clampbar being released and allowedto fall to a positionto the rear'of the shock and act as a guide for thesheaves while the shock is being assembled.

In order to start the platform on its rearward movement at the propertime, I employ a pivoted bar 225, carried by a standard 226 V to thebell-crank lever 118, which controls the movement of the latch-bar 105.When the latch-bar 225 is raised by the engagement therewith of a pawl220' on the upper portion of the rack-bar, the position of the clutch ischanged in the manner previously described and the platform is returnedto its initial position while the frame 175 is traveling toward thefront of the machine. When the frame 175 reaches its full forwardposition, the lugs 193 on said frame engage the slidable bars 192 andthrough the rock-shaft 190 and arm 198 depress the bell-crank lever 188and remove the clutchingsleeve 187 from ongagement with theclutching-sleeve 188 from the shaft 130. This stops the movement of theframe and forks with the parts in the position illustrated in Fig. 15.As the platform is returning to initial position it operates theclutching mechanism controlling its own movement and then serves torotate the ratchet-wheel 77 to the extent of one tooth, moving therecessed portion of the cam 82 out of contact with the arm 83 andunclutching the shaft 28 from the constantly-revolvin g spocket-wheel29, thus stopping the movement of all parts of the machine with theexception of the mechanism for receiving and delivering the shocks tothe platform and for revolving said platform. At the completion of theplatform movement the lever 157 is released from the spindle 146 of theshockformer 145 and the latter descends by gravity, its legs beingautomatically spread at the center of the platform and all of the partsbeing thus returned to a normal position in readiness for the formationof a fresh shock. While the construction herein described andillustrated in the accompanying drawings is the preferred form of thedevice, it is obvious that various changes in the form, proportions,size, and minor details of the structure may be made without departingfrom the spirit or sacrificing any of the-advantages of the invention.
